Application filed November 18, .1921. Serial No. 516,054.

To all whom it may concern:

Be it known that I, JOHN F. STEoxnNRnI- TER, a citizen of the UnitedStates, and a resident of the city of New'YorlQ'borough of Brooklyn,Flatbush, in the countylof Kings and State of New York, have invented anew and Improved Sill Construction, of which the following is a full,clear, and exact description. r

proved construction for'windows, and has for an object the provision ofa sillconstruction whereby the lower sash member particularly can beoperated very easily and simply and when closed form a .very tightmanufactured sill is very readily adapted to a window opening and can bequickly and easily applied to the jamb members, substantially all ofwhich is made of ordinary common stock material thereby reducing theexpense of manufacture.

A further object resides in the provision of a combination of the silland jambs and lower sash of a metal window whereby all the practicalrequirementsv are sati'sfied'and the combination is easilyand-economically assembled.

A still further object resides in the particular construction andarrangement of parts which are hereinafter described and claimed andshown in the accompanying drawings.

The invention-is illustrated inthe drawings, of which r Figure 1 is aplan ofthe window opening showing the silland the lower portion of.

two hollow metal jambs and k the window sash in section; I

Fig. 2 is a partial rear elevation of the sill and the jamb; and

Fig. 3 is a vertical transverse section taken on the line 3-3 of Fig- 1showing the sill,

V hollow metal jamb and the windowsa'sh in its closed position.

As shown in the drawings the prefer-red form of the invention is" setforth, although minor modifications may be made in thec onstruction andarrangement of the parts without departing from the spirit of theinvention. The sill 1 extends across thewindow.

opening between the jamb 2and the j amb 3. It has at each end thereof adownwardly extending fiange portioni l which is fastenedto the jambsby'means of tie "rods such as 5 and 6 which pass under the sill throughthe flange and tlie'j'jamb'members and extend withinthe j'amb membersand are threaded on their ends to receive nuts suchias 7. fDisposedbetween the nuts 7 and the jamb members are flat plates 8 which'a'ctsomewhat "in;

thev fashion of washers. The flanges 4 of the The invention relates to'anew and im-,,

jolts of handlingand shipping, tie r'odsare Y preferable. These rods,furthermore, may ac't'as anchors for cement where -the under side ofthe'sil lis grouted; This ifiange f also provides ample surface forapplying any plastic substance, such as putty, to make a watertightjoint between th'e'j'amb' andthe sill. I

as indicated in Fig. 1, across the a window opening,to a plaster linesuch as 10, at each end of the. sill,fa nd is provided with a suitablecurved molding-1 1 on the rear edge. The horizontal portions of the sillwhich are disposed adjacentthe rearface of the jamb and the asta-1111910are called the stools 12. 'Beneath these stool porti( );1, 1SV are: disposed lugsfor bracket members '13 whichex tend downwardly therefrom andmay be bolted to the jamb to give additional support and stiffness/tothe, Structure. f

On the top of the'sill, onthe'front edge of the fiat portion 9, is acondensation gutter 'or'groove 1} Throughout the lengthiofthis grooveare provided a plurality qfapertures.

1 5. are generally called weep-holes. This groove His adapted t0"receive0 iS ture dueto condensation orotherwisebn the window and; permits it toas's through these holes .to. a point connected. with the downwardlysloping surface 16 of the sill whereby it canrun out of the window. Thesill is provided with vertically extending faces or shoulders, such as17 andl8, and a horizontal face 19. The lower rail-o'fthelower sash isformed of a U-shaped channel member 20 having downwardly extending limbportions 2 1 and 22, thelimb' portion 22 facing the outside or front ofthe window projecting The. sill 'extendsalong its rear portion 9, i

further down than the limb portion'21' and is adapted to bear againstthevertical wall 18 andrest on. the surface l9,whereasthe limb 22rests'on the sloping surface 1 '6 and ns e S w nthisi -ay i il of thesurface 23 extending from the surface" 19 to the front of the sill. Thispitch is required so that the sill will shed the'water readily towardthe front of the window.

The fiat plates 8 previously mentioned act as washers which, under thepull of the tie rods draw the jamb hard up against the sill at allpoints to make a water-tight connection.

It is clear that under this construction the jambs do notrest upon thesill but that the sill is coped to fit around the The jambs thus passingby the sill down to the wall upon which the sill: rests results in agreat advantage to the construction by reason of the additional andmaximum space afforded in the jambs for the sash weight (not 7 shown) Itwill therefore be observed that l have provided a simple andeconomically constructed, strong and durable window constructionespecially relating to the lower sash, the jambs and the sill, wherebythe contact between the sash and the sill is made very tight to preventleakage of air and moisture therethrough and in which the sill *isveryeasily connected to the jamlo members.

It should be borne in mind,.of course, that the stool can be madeseparate from the remainder of the sill for practical reasons, such asto avoid breakage and for convenience in shipping. Furthermore, a metalstool may not be desired, since thestool may be finished in marble orother material. The sill proper may, of course, be made of rolled steelinstead of being cast.

The vertical shoulder 18 may, as shown in the drawings, be extendedupward some distance above the level of the sloping surface 16. 7

What I claim is:

1. A sill made of metal having downwardly projecting end flanges fordisposition against a hollow jamb member, a plurality of tie rodsextending across between and through the flanges, the ends of the tierods extending within the jamb members, and means on the ends of the tierods to fasten them to the j amb members.
